No, KFC is not an Israeli brand. It is an American fast-food chain.
KFC Corporation, operating as KFC (Kentucky Fried Chicken), is a globally recognized fast-food chain originating from the United States. While KFC has a presence and operates restaurants in Israel, it remains an American company. Its headquarters and core operations are based in the United States, and its branding, menu, and business strategy are centrally managed.
Therefore, despite having locations in Israel, KFC's origin and ownership are decidedly American.
